Do i need a tetanus shot? i just stepped on a tack my heel area.it had been used to go in the wall but is not rusted.(newly diagnosed type 2 diabetic)

Any break in skin: The spores of tetanus are similar to any bacteria in their ability to enter a break in the skin and begin thriving on the juices therein.As the germ spores begin to form an infection, it will eventually be able to make tetanus toxin and cause tetanus.Some injuries are more likely than others to expose you to tetanus, but any break in the skin might.A booster every 10 yrs is simple protection.
